Auto-Sensing 28.5 Volt DC Aircraft Ground Power Unit (GPU) Cable Assembly with control lead.
This remote sensing cable with sensing lead is intended for use on Davco or Tug Tech GP28M Magnum 28V DC ground power units. This cable remotely senses voltage drops at the plug and regulates the voltage going into the aircraft on GPUs that have limited engine controls. The sensing lead ensures a 28.5 volt power supply when the GPU is under load during aircraft engine starts.
Is it time to replace that worn aircraft GPU cable? This easy-to-install GPU cable connects to the GPU power supply to the aircraft. Our DC GPU cable assembly has positive and negative battery terminals at the supply end of the cable with a molded 3-pole 28V DC aircraft plug that attaches the GPU to the aircraft.
Constructed of a proprietary synthetic elastomer, the molded aircraft plug/head has excellent moisture, chemical and abrasion resistance qualities. Each connector has silver-plated tellurium copper contacts with quad beams and engineered steel springs that assure consistent contact for thousands of cycles. Silver-plated tellurium copper contacts reduce contact electric resistance.
Our auto-sensing 28.5V DC Aircraft GPU Cable Assembly consists of (2) insulated 4/0 copper wires and (1) 8/1 AWG control lead bound with a non-metallic band. Attached is a 3-pole molded sensing aircraft plug/head.
Meets MIL-C-7974D, MIL-C-5756, MIL-STD-810F, MIL-C-81790 standards.
Be aware that a longer replacement cable than what was initially designed for your GPU may degrade the performance or require an adjustment to the voltage compensation parameters if your GPU is equipped with this feature. This performance impact is due to voltage line drop, which varies with the length of the cable.
